Persicaria tinctoria is a species of flowering plant in the buckwheat family. Common names include Chinese indigo, Japanese indigo and dyer's knotweed.[2][3][4] It is native to Eastern Europe and Asia.
The leaves are a source of indigo dye. It was already in use in the Western Zhou period (c. 1045–771 B.C.), and was the most important blue dye in East Asia until the arrival of Indigofera from the south.
